You can find the detection logic for this version at commit a1e47cb. For merge requests, please use the latest version in the Lintian check debian/copyright/dep5.
Your copyright file references a license that is not defined. Due to copyright law or treaties, files that are not available under a defined license are non-free and non-re-distributable.
Referencing an undefined license could mean the file cannot be distributed in Debian or it could simply mean that the existing license needs to be documented. In both cases, the copyright file should be updated to reflect reality.
Please re-package the package without the file (if possible) or ask the FTP-masters to remove the package.
If the package has been uploaded to Debian before, and if affected files cannot be distributed in Debian please remember to also notify snapshot.debian.org about this package containing a non-distributable file.
